Corrosion Analysis and Control of Atmospheric Column in a Large-scale Oil Refining Corporation in China

Serious corrosion of atmospheric column were found during the investigation of corrosion of the crude unit in a large-scale oil refining corporation in China in 2013. According to the equipment′s design parameters, process parameters, analysis data of crude and sewage, the risk-based corrosion analysis for the corrosion components were made. The failure mode and the damage mechanism of the components were identified. According to the results of the analysis, suggestions for corrosion control were put forward.
